Constable Shiva Prasad had gone to the complex along
with Sub-Inspector Nagender Rao following a complaint of a
quarrel between two groups, Asifnagar division Assistant
Commissioner of Police L T Chandra Sekhar said.

"When police tried to pacify the groups, Khan along with
his supporters reached the place and picked up an argument. He
then held the collar of the constable and slapped him," police
said.

"We have booked a case against the MLA under Section
353 of IPC (Assault or criminal force to deter a public
servant from discharging duty)," he said.

As the news of Khan`s arrest spread, his supporters
assembled in large numbers and staged a sit-in raising
anti-police slogans in front of Humayun Nagar police station.

Khan has been involved in several controversial cases,
including the attack on Bangladeshi writer Taslima Nasreen at
the Press Club here in 2007.
